Dualboot Windows 7 & Ubuntu 12.04 LTS with a HDD for win and ssd for ubuntu

[thedual5s]

Good day,


I have been trying to setup a dual boot system with windows 7 installed on a 1TB hard drive and ubuntu installed on a 120GB SSD. I have done alot of reading and have also come pretty far, but I am stuck. below is what I have done and some various info about my setup


Sata0 - 1TB HDD
Sata1 - CD/DVD Burner
Sata2 - 120 GB SSD
Motherboard: Asus 990FX
UEFI

1. Installed WIndows 7 on to the 1TB Drive, This is while in UEFI the SSD is set to Primary boot device.
2. reboot and varify that the SSD is still primary boot device, it is not. EUFI won't allow me to make it primary, I'm guessing because nothing is on it so it recogognizes that.
3. I go ahead and boot to the Ubuntu CD and install Ubuntu on the SSD with a 500MB /boot, a 32GB /swap and the rest as /. reboot
4. go into UEFI and put the SSD as primary boot device. no problem. reboot.
5. machine boots right into Unbuntu with out the grub boot menu, no big deal, tried holding down shift while reboot, still no Grub boot menu.
6. booted to live Ubuntu and installed boot repair, it ran without issue and gave me http://paste.ubuntu.com/5843951/ as the trobleshooting file. I now get a GRUB boot menu and Ubuntu works fin, but when I try to use any of the 3 options refereing to windows, I get: Error: no such device: UUID (I can't remember the UUID at this moment but can grab it when I reboot.)

the exact error is:

error: no such device: UUID
error: file not found

press any key to continue....


This is where I am at. Any assistance would be greatly appricaited. Let me know if you need more information. Thanks for you help.

Welcome to the Ubuntu Forums :-)

1. Did you install Windows 7 yourself? Then I suggest that you install it without UEFI (if you can set the BIOS in another mode, sometimes called CSM). This will make it much easier for you.

2. But if the computer came with Windows preinstalled in UEFI mode, you have no choice.

3. In UEFI mode: Shut off secure mode if possible, shut off fast boot if possible.

4. You need a gpt partition table (not the standard msdos one with mbr) for all drives with operating systems to be booted.

Thank you for the quick reply. I beleive that both boot partitioins are GPT. Secure mode and fast boot are both turned off.

2. /dev/sdb has an extended partition. This is a feature of msdos partition tables, so it is not gpt. It will not work in UEFI mode. You can create gpt with gparted, but you must select advanced for the partition table.

Your HDD has GPT but your SSD has 'msdos' partition table. You have to change this to GPT. Both OS must be installed in either UEFI or Legacy Bios. To Boot in UEFI you must have Ubuntu installed in UEFI mode.

Using Gparted Delete all the partitions on SSD and change the partition table to GPT. This can be done with Gparted -> Devices -> create Partition Table. GPT will be under advanced options.

After which create the first partition of about 300MB and format it with FAT32, create other partition you need then Reinstall ubuntu. If you have trouble booting windows then run Boot-Repair.
